1 Channel Status
The status of each channel is shown by the three
indicators below.
Red: Short circuit on an output line
Red: Clipping on speaker output
Battery status: Blue=OK; Red = Low
2 Speaker Load Setting
You need to select the speaker load being
connected to each output for power supply
matching.
Connecting lower impedance loads (ex. 2Ω) will
result in an appropriate internal voltage
adjustment. In case of mismatches, the
following protection mechanisms may
automatically apply:
1. The amplifier will reduce the output power.
2. The amp shuts down to safe mode. The amp will
only recover after reboot (off/on). Impedance
settings are to be carefully reviewed in such
case.
3 Parallel Mode
With this setting you can select the desired
channel pairs to enter parallel mode. This would
on the one hand reduce the number of
independently available output channels, but
on the other hand improve the output's
damping behavior. It virtually shares the
connected load among the two paralleled
22
-EN
outputs (ex. a connected 2Ω load would appear
as 4Ω to each of the two paralleled outputs).
4 System Monitor
This section allows to check the battery voltage
of the vehicle and the temperature of the
amplifier.
5 Live Monitor
This tool allows you to monitor the average
temperature and voltage over a period of 1, 3 or
5 minutes.
